C. diff. Infection and Sepsis Overview During a One Year Follow Up

Sepsis was a common Clostridioides difficile infection (C diff) complication throughout a 12-month follow-up period and was most commonly observed in the cohort of patients with 3 or more C diff infection recurrences, according to a paper published in SAGE Open Medicine.

Investigators from around New England conducted a retrospective analysis of more than 46,000 adult patients with C diff infection in order to evaluate the clinical complications of C diff in patients with index and recurrent cases. The investigators used the IQVIA PharMetrics Plus database to looks for patients aged 18-64 years with an index C diff episode that required inpatient stay or an outpatient visit, followed by a treatment for the infection. Treatments included vancomycin, fidaxomicin, metronidazole, rifaximin, or bezlotoxumab, or fecal microbiota transplant (FMT – though it was rare).

Each infection ended after a 14-day C diff-free period was observed, leaving recurrent C diff to be defined as further infection within an 8-week window for a period of 12 months.

A total of 3129 patients (6.7%) experienced 1 recurrence, while 1% had 2 recurrences, and 0.3% had 3 or more recurrences. The study authors also noted that autoimmune diseases, such as ulcerative colitis, Crohn’s disease, type 1 diabetes, rheumatoid arthritis, and multiple sclerosis, were present in 18%, 23%, 24%, and nearly 40% of patients, respectively, in patients with 0, 1, 2, or 3 or more C diff infection recurrences.

Antibiotics were prescribed for three-quarters of all patients in all groups in the 6 months preceding the index C diff infection, the investigators found. Gastric acid-suppressing agents were prescribed in 28%, 33%, 39%, and 38%, respectively, in patients with 0, 1, 2, or 3 or more C diff infection recurrences, the study authors also noted.

Vancomycin was used to treat about a third of all index C diff infection patients, while metronidazole was used to treat a little more than half of the patients, the study authors wrote. Fidaxomicin was used to treat about 4% of patients. Vancomycin was the most commonly prescribed antibiotic used in recurrent C diff cases, with 55% of patients getting the antibiotic for the first recurrence, 56% getting it for their second recurrence, and 60% getting it for their third recurrence.

During the 12-month follow-up period, the investigators observed sepsis in 16%, 27%, 33%, and 43%, respectively, in patients with 0, 1, 2, or 3 or more C diff infection recurrences. No patient had more than 2 sepsis episodes during the 12-month follow-up period. Additionally, subtotal colectomy or diverting loop ileostomy was performed in 4%, 7%, 9%, and 10% of patients, respectively, in patients with 0, 1, 2, or 3 or more C diff infection recurrences.

“Our findings indicate that, among patients with more recurrent C diff infection, there was a parallel trend for higher rates of colectomy and sepsis,” the study authors wrote.

The study authors also said that patients with 3 or more recurrences also had the highest health care resource utilization and total, all-cause, direct medical costs of all the recurrence cohorts. Sepsis was highest among this group with the most recurrences, and the study authors hypothesized that this was due to having more opportunities to suffer from this type of adverse outcome.

“Reduction in recurrent C diff infection may be an important step to reduce the burden of serious clinical complications,” they concluded.

Proton-Pump Inhibitors and Increased Risk of C. diff. Infections

 

 

 

 

 

Increased risk for Clostridium difficile (C diff) infection remained elevated for up to a year after the conclusion of treatment with proton-pump inhibitors (PPIs), according to a paper published in Clinical Infectious Diseases.

Investigators from Copenhagen, Denmark used a nationwide cohort of adults with
a C diff infection in order to compare periods with and without exposure to PPIs. The adults were all treated between February 2010 and December 2013. The nationwide database included health information such as C diff testing, filled prescriptions, and patient characteristics. The investigators also accounted for the previous hospitalization in the previous 12 weeks in the patients, in addition to chronic disease, genetics, socioeconomic status, length of hospital stay, and antibiotic and corticosteroid use.

Ultimately, the study authors identified 3583 episodes of community-acquired C diff infection, of which 964 occurred during the current use of PPIs. This is an observation in the current literature, but what wasn’t understood was the full extent of the relationship due to missing data from randomized controlled trials, variability between studies, and insufficient adjustment for confounding.

“While a history of prior hospital admission, advanced age, and antibiotic use are well-known risk factors for C diff infection, the role of PPIs has remained controversial,” the study authors wrote.

The investigators defined new PPI use as a new prescription for individuals who had not used PPI in the prior 365 days. They split up the periods of 0-6 months and 6-12 months because in the first period, cessation was considered indeterminate use because of the possibility for intermittent use or drug exposure continuing beyond the use period. Exposure during the 6-12 month period was “unlikely.”

Of the infections that occurred with the use of PPIs, 324 occurred within 0-6 months after treatment conclusion. Additionally, 123 cases occurred between 6 and 12 months after treatment cessation.

The remainder of C diff infection cases occurred during time periods without use of PPIs, the investigators said.

Comparing the use of PPIs with nonuse, the study authors found that the adjusted estimate incidence rate ratio (IRR) was 2.03, they said. But the risk remained elevated in later time periods too: 1.54 for 0-6 months and 1.24 for 6-12 months.

“In conclusion, in this nationwide study in Denmark, we showed that exposure to PPIs was associated with a moderate increase in the risk of community-acquired C diff infection,” the study authors said while noting that the mechanism by which PPIs may increase the C diff infection risk remains unclear. “The increased risk was most prominent during current PPI use but also persisted after treatment discontinuation.”

One limitation the study authors provided for was that initial symptoms of C diff infection could have been misinterpreted and patients prescribed PPIs could not be excluded. But, they also admitted, “it is unlikely that this would lead to biased results because the symptoms of C diff infection (diarrhea) are distinct from the upper gastrointestinal symptoms that represent the most common indication for PPIs.”
